Abstract
En 中文
Objective:This study aimed to develop and validate a questionnaire assessing the nutrition knowledge (NK) of Italian adult women regarding the relationship between diet; lifestyle and bone health.Design:A thirty-item questionnaire in Italian was developed by experts based on a literature review. Participants completed the questionnaire twice; with a 2–4 week gap between the two administrations. During the initial administration; weight and height were recorded using a mechanical scale and a stadiometer; while bone mineral density (BMD) of the lumbar spine (L1-L4); femoral neck and total femur were assessed via dual-energy X-ray absorptiometry (DXA).Setting:Centre for Metabolic Bone Diseases at the Parma University Hospital; from January 2022 to June 2024.Participants:Women aged 45–75 years old; native Italian speakers; undergoing DXA at the Centre participated.Results:The sample included 295 women with a median age of 63 years (interquartile range 11·5). The questionnaire demonstrated good internal consistency (Cronbach’s alpha = 0·698) and high temporal stability (R = 0·810; P = 0·002); effectively differentiating between individuals with and without a nutritional background. Regression analysis indicated negative associations between NK score and age (β1 = –0·130; P < 0·001) and BMI (β1 = –0·193; P < 0·001).Conclusions:The NutriBone questionnaire is a valid and reliable tool for evaluating NK related to bone health in Italian adult women undergoing DXA; with potential for future research applications.
